Abstract

Naphthalene, a widely used industrial chemical and a popular household insecticide or repellent is an uncommon agent of poisoning worldwide. The usual toxic manifestations range from mild gastrointestinal symptoms like recurrent vomiting, and pain abdomen to severe multiorgan failure including severe haemolysis, acute kidney injury (AKI), hepatitis and methemoglobinemia. The commonest causes of poisoning include deliberate self-harm and accidental industrial overdose. We report a successful management of a rare case of naphthalene toxicity presenting with severe haemolysis, methemoglobinemia and multiorgan failure. Prompt identification of methemoglobinemia and immediate administration of specific antidote methylene blue along with blood transfusions and other supportive care holds the key to successful outcomes.
